a. minute. It has been found in practice that a steam pressure of substantially sixty into small pieces.

pounds and the constant temperature of 212 degrees Fahrenheit for a period of thirtyfive minutes will produce the desired result.

After the pressed cakes have been re- .rnoved from the presses 17 and the press cloths stripped from the cakes, they are placed upon a scale 18 and -weighed to determine the quantity and condition of the product, after which the cakes are fed to a breaker 19 where the same are broken up From the breaker the food is discharged into a bin 20 and is now in condition for delivery. If, however, a meal is desired, the broken pieces of cake are fed to a mill indicated at 21 which thoroughly grinds the sarnef/ In' this condition the product may be i' d for a cattleI food or for any other purp se for which cotton seed meal is now generally used.

From the foregoing it will be seen that I have produced a process for the manufacl" ture of4 stock food fromlthe residue of the cotton seedafter the oil has been extracted which will be, rich in protein and fat and owin to the manner of mixing the meat and ulls, a homogeneous uniform food product is obtained. Under the present system of producing such stock foods, uncooked hulls are sometimes mixed with the meat, but these uncooked hulls are of low food value, and much loss is also occasioned by the necessary mixing of the same with the seed meat. I am also aware of the fact that the wholeseed has been cooked together with the hulls thereof, but in such instances it has been discovered that the proportion of the hulls or crude fiber is too great and the protein component of the result-ant food is lowered to such an extent as to produce a product whichv is of very low food value. By means of my improved process, the hulls and meat are scientificallymixed in proper proportions so that the desired results may be obtained in the fattening of live stock. As the hulls have been thoroughly sterilized and cooked, all disease germs which might be contained therein in the raw state of the hulls are killed so that a thoroughly healtht ful and sanitary food ready for use when the same leaves the mill is produced.

Of course the condition of the cattle at the expiration of a predetermined length of time after they have been fed wi-th my improved roduct, willA disclose to the owner whether 1t would b'e desirable to increase or decrease the quantity of seedhulls, and rthe proportion .of the hulls to the seed meat may then be varied to vmeet requirements..

Having thusdescribed the invention, what' is claimed is: l

1. A sub; .recess employed in obtaining stock food rom cotton seed which consists in first cleaning the seed, then removing the lint therefrom, thenl hulling the seed, rolling the meat and hulls together and mixing the meat with the hulls, cooking the mixture for a predetermined ltime and maintaining the same in an agitated condition while cooking.

2. The hereindescribed process of extracting oil from cotton seed which consists in first cleaning the seed, then delinting the same, then hulling the seed, crushing the meat and hulls together and mixing the crushed meat and hfills, said hulls formingr P not less than thirty per cent. of the mixture,

then cooking the same for a. predetermined time and maintaining the mixture in an agitated condition while cooking, then preparing the cooked mixture for the press and pressing the oil out of the meat and hulls.A

3. The hereindescribed process of obtaining stock food from cotton seed which consists in cleaning the seed, removing the lint therefrom, then hulling the seed, rolling the meat and hulls together and mixing the same, then cooking the mixture under' a steam pressure of approximately sixty pounds for a period of substantially thirtyfive minutes and maintaining the mixture in an agitated condition during the cooking thereof, then pressing the cooked mixture to remove the oil therefrom, and finally omminuting the pressed mixture for stock ood.

4. The hereindescribed process of extractving oil from cotton seed which consists in ing stock food from cotton seed, which con-v sists in removing the lint and motes from the seed, hulling'the seed, then rolling the meat and hulls together and mixin hulls and meat in a raw state, said mixture containing not less than thirty per cent. of the hulls, then cooking the mixture, then pressing the oil from the cooked meat and ulls, and finally comminuting the resultant product fdr stock food.
